You can find my thread in the "Divorced, but not done" group under the title "The fat lady is warming up...2".
I hear what you're saying, but I remain unconvinced. Of course, each situation and the people involved are unique so, as they say, your mileage may vary. However, I know of two or three people here (I wish I could remember which threads they were) who were full-tilt to moving back in when the WAS flipped out and everything fell apart. That doesn't mean it's over for them, but I'm sure you can understand they were devastated by the turn of events and I think they'd agree it was a significant setback.
It's also worth noting that when you go back to living together, keeping on the right track (at least on your end) will be more difficult as well. Still, your situation may, indeed, be unique. We can all offer advice, but at the end of the day, you have to do what you feel is right. There's no OW, right? That is to your favor. Very hard to successfully get back together with someone else waiting in the wings (so to speak).
